SHEET-DEFLECTING DEVICE.

To all whom it may 007106771.

Be it known that I, JACOB GRooM, a citizen of the United States, and a resident of Pearl River, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Sheet- Deflecting Devices, of which the following is a full and clear specification.

This invention relates to sheet deflector devices for folding machines, the primary object being to provide improved means for tipping-in the edge of a sheet which is to be passed through the folding rollers without being folded. An operation of this character is frequently desirable where a single insert sheet is called for and the present invention contemplates an improved construction and mounting for a tipping-in attachment according to which the deflector, which constitutes an essential part thereof, can be readily moved into position when re quired and as readily removed when the occasion for its employment has passed.

Collateral and incidental objects of the invention will appear in the specification and be pointed out in the appended claims.

The preferred embodiment of my improved tipping-in attachment, is shown on the drawings which constitute a part of this specification.

In the drawings,l*1gure 1 is a front plan view of the attachment in service position, showing its relation to a pair of folding rollers, parts being broken away and parts shown in section. Fig. 2 is an end elevation of the same including a fragmentary showing of the folder blade; Fig. 3 is a view similar to Fig. 1 with the parts in nonservice position permitting a simple fOlCllllQ' operation between the folding rollers; and Fig. 4 is an end elevation of the device according to Fig. 3.

Referring more particularly to the drawings, a pair of folding rollers 1 which are usually rotatably mounted in suitable bearings (not shown) by means of end journals 2, are cooperatively arranged with respect to the folding blade 3 which as usual is suitably mounted on one or more blade-supporting arms 4 which may be caused to rise and fall by any suitable operating mechanism (not shown).

In the present embodiment of my invention, a cross bar 5 which extends across Specification of Letters Patent.

the folding machine, may be mounted in any suitable manner to adapt it to constitute a rigid support for the tipping-in attachment. Journaled within this rigid support are a pair of laterally projecting pins or rods 6, each of which is provided with a head 7 which bears against the outer face of the cross bar 5 and thus serves to pre vent a lateral displacement of the deflector blade (to be presently referred to) in one direction. Rigidity secured to the ends of said pins or rods 6, are the plates or arms 8, each of said arms or plates 'being pivotally connected at 9 to the deflector blade 10 so that as said blade is raised and lowered in the manner indicated in Figs. 1 and 3, it is maintained with its lower edge substantially parallel to the axes of the rollers 1.

By an inspection of Figs. 2 and 4t, it will be noted that the deflector blade 10 is provided with a beveled lower edge 11 so disposed that the flat face thereof is adapted to lie closely against the lateral face of the folding blade 8, in its lowered position. In order to provide simple and efficient means for raising and lowering the deflector blade 1.0, a hand lever 12 is fixed to one of the pins or rods 6, said hand lever being pro vided with an integrally formed sector arm 13 having an arcuate slot 14 therein. Threaded into the crossbar 5 is a clamping screw 15 provided with an integral collar 16 which is adapted to clamp the slotted arm 13 between it and the crossbar 5 to retain the deflector plate in the position to which it has been moved.

What I claim is:

1. The combination with suitable folding rollers of suspension links movable about axes transverse to said rollers, and a deflector blade pivotally suspended from the depending ends of said links to adapt it to be swung in substantially the tangent plane of said rollers into and out of position to deflect sheets into the bight of said rollers.

2. In a machine of the character described, the combination with suitable folding rollers, of a support, pins or rods journaled in said support and extending transversely of said rollers, a deflector blade movable into and out of sheet-deflecting position adjacent said rollers, arms depending from said pins or rods in approximately the tangent plane of said rollers, said deflector blade being pivotally connected to said arms, and means for moving said deflector blade.

3. In a machine of the character described, the combination with suitable folding rollers, of a support, pins or rods journaled in said support and extending transversely of said rollers, a deflector blade movable into and out of sheet-deflecting position adjacent said rollers, arms depending from said pins or rods in approximately the tangent plane of said rollers, said deflector blade being pivotally connected to said arms, and means for moving said deflector blade, said means including a hand lever rigid with one of said pins or rods.

4. The combination with suitable folding rollers, of a fixed support arranged above said rollers, a deflector blade extending lengthwise of said rollers, said blade being movable in the tangent plane of said rollers into and out of sheet-deflecting position, and

means for shifting the positions of said deflector blade, said shifting means including a hand lever movable in a plane parallel to said tangent plane. v

5. The combination With a folding machine embodying suitable folding rollers, of a tipping-in attachment therefor comprising a fixed support, pins or rods projecting from said support, a deflector blade swingingly suspended from said pins or rods, and means for swinging said blade into and out of sheet deflecting position with respect to said rollers, said means including arms fixed to said pins or rods and pivotally connected to said deflector blade, and a hand-lever v,

fixed to one of said pins or rods.
